Some globals are static and it doesn't make sense to destroy them before
the wl_display. For instance, wl_compositor should be created before the
display is started and shouldn't be destroyed.
For these globals, we can simplify the code by removing the destructor
and stop keeping track of wl_resources (these will be destroyed with the
wl_display by libwayland).
The documentation for wayland-server.h says:
> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.
Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.
Since the fullscreen request may be made before the toplevel's surface
is mapped, the requested fullscreen output needs to be stored so it
can be retrieved on map (along with the existing fullscreen property).
This commit makes the required changes for wlr_xdg_toplevel_v6.
This introduces -DWLR_USE_UNSTABLE and adds information regarding the
stability status to all headers. I started with a conservative set of
headers to mark as stable:
- types/wlr_matrix.h
- util/edges.h
- util/log.h
- util/region.h
- xcursor.h
It is common to want to iterate an xdg-surface's popups separately from
the toplevel and subsurfaces. For example, popups are typically rendered
on top of most other surfaces.
wlr_xdg_surface_for_each_surface continues to iterate both surfaces and
popups to maintain backwards compatibility.
The motivation for this is:
- `get_popup` and `get_toplevel` allocate role-specific resources.
- On the first non-null commit, the surface gets mapped.
- On a null commit, the surface gets unmapped. It can be mapped
again with a non-null commit.
- When the role object (xdg-toplevel or xdg-popup) is
destroyed, the surface is unmapped and role-specific resources
are destroyed. The client can call `get_popup` or `get_toplevel`
again on that surface.
- When the xdg-surface object is destroyed, the surface is
unmapped, role-specific resources are destroyed and the surface
itself is destroyed.
